"It was so weird, it didn't even feel like we were doing a 'Twilight' film. I was like, 'Bella! What are you doing? Wow! What is happening here?!'" the 21-year-old actress told the UK edition of Glamour in its December issue, when asked about the movie's sex scenes.

"It was very surreal. We [originally] got rated R. They re-cut it," she explained of the movie, which also stars boyfriend Robert Pattinson and Taylor Lautner.
